That power for Paredes has disappeared as suddenly and mysteriously as it appeared and if you check his game logs for July you will find that the Rays have him playing the worst ball of his career right now. He is also spending significant playing time at first base, which suggests that the Rays aren't sure where he fits defensively, which sounds familiar.
As of now, with almost equal playing time in each organization, his BA and OBP are virtually identical for both teams. His SLG is quite a lot higher with the Rays of course, primarily because of that 4 game stretch where he went 10 for 15 with 5 home runs. That was the week in which the Rays had "unlocked" him and "fleeced the Tigers" and so on, but in reality other than that week he's pretty much the same as he ever was. He's a guy with some talent, with an uncertain defensive profile, who doesn't get on base often enough.
That is disappointing because I was hoping that he would hit 25 home runs and earn a nice payday, but that isn't going to happen.
